KROK 1 2018 – Question 97 · KROK (Medicine) · Physiology
A woman with the III (B), Rh (-) blood group gave birth to a child with the II (A) blood group. The child is diagnosed with hemolytic disease of newborn caused by rhesus incompatibility. What blood group and Rh does the father have?
- A. II (A), Rh (-)
- B. III (B), Rh (+)
- C. II (A), Rh (+)
- D. I (0), Rh (+)
- E. I (0), Rh (-)
Hint
Work out which ABO allele the father must have supplied from the child's and mother's groups, then decide what Rh type he needs for a rhesus conflict to occur.
